Musannaf Ibn Abi Shayba 28:37

'Abd al-Rahim ibn Sulayman narrated to us, from Muhammad ibn Ishaq, from Yazid ibn Abi Habib, from Abu Marzuq, the freed slave of Tujib, from Hanash al-San'ani, who said: We went on a military expedition with Ruwayfi' ibn Thabit al-Ansari toward the Maghrib, and we conquered a village called Jarba. He stood among us as a preacher and said: I do not say to you anything except what I heard the Messenger of Allah (may Allah bless him and grant him peace) say to us on the day of Khaybar: "Whoever believes in Allah and the Last Day, let him not ride a mount from the spoils of the Muslims until, when he has made it lean, he returns it to it (the spoils). And let him not wear a garment from the spoils of the Muslims until, when he has worn it out, he returns it to it."
